How does a CDI work on a motorcycle?
Working principle a CDI System. A capacitor discharge ignition works by passing an electrical current over a capacitor. This type of ignition builds up a charge quickly. A CDI ignition starts by generating a charge and storing it up before sending it out to the spark plug in order to ignite the engine.
What happens when a CDI box goes bad?
Sometimes, a bad CDI does not cause sparks at all. Again, when a CDI box is about to go bad, it can lead to misfires, issues with starting, rough running or even stall the motor. These mentioned symptoms can be confusing and one has to be careful before concluding that the problem is with the CDI.
Can a bike run without a CDI?
Yes, you can with a mechanical unit. But customizing one will take lots of time and effort. It might be even more costly to custom build one as the CDI on the market shelf is mass produced one hence efficiently produced. That will keep it’s price reasonably low.
Are CDI boxes interchangeable?
as long as you stay with ac or dc (depending on what the cdi needs/your stator output) and the trigger type is similar, you can pretty much make anything work.
What’s the difference between CDI and ECU?
CDI is Control Digital Injection sysyem and controls various ignition aspects and ECU which is an Electronic control unit which controls the whole running, memory and mapping.
Can a CDI box cause weak spark?
Yes, a poor cdi can cause a weak spark.

How do I know if CDI is not working?
Determining whether your motorcycle’s electrical problems are due to a malfunctioning CDI box can prove complicated.
There are some symptoms of CBI box malfunction, including:
- Rough running.
- Difficulty starting.
- Other ignition problems.
- Engine stalling.
What does a unrestricted CDI do?
What does a unrestricted CDI do? Without spark, the engine slows to below the “rev limit” and the CDI resumes providing current. An unrestricted CDI does not stop providing current no matter how high the engine rpms go. You are only limited by the engine itself.
Which is best TCI or CDI?
CDI’s have very high spark voltage compared to TCI, but CDI also has a very short spark duration. CDI powered coils also can be used in higher rev situations because the coil isn’t dependent on time to build up inductance in the secondary coils, it is amplitude dependent.
